XOR behaving strangley

[alecjcook]

65 XOR 0 = 65... why does labview think the answer is -66?!

Nope...thats an XNOR, so it makes sense.

You're doing a XOR which is 65 yes, but then a NOT after that.  So with I32's (signed), that makes -66.

65 XOR 0 = 65

NOT (65) = -66

xor

00000000000000000000000000000000

=

00000000000000000000000010000001

NOT =

11111111111111111111111101111110

which is a negative number with the absolut value

00000000000000000000000010000001

+

00000000000000000000000000000001

=

00000000000000000000000010000010

So -66 is correct.
